Controls
Go to Arcade mode. If you lose to your rival character the game (if you wanted I-ISM pluses), drop the continue numbers to 0 very fast. You will get a game over with a 'Try Again' on the middle. When you move the D-pad the buttons are glitched. If you want to cancel it, you can press Home and get out of the game or by turning the power off.

Unlock ISM Plus upgrades
Even after completing World Tour Mode, there are more ISM Plus upgrades to unlock for your World Tour character (or to be used for any character created in Edit Mode). To unlock these, save your game after completing World Tour Mode and register your World Tour character in Entry Mode. Now use that character in other modes to unlock the ISM Plus upgrades.
